Contaminants of Emerging Concerns and Reigning Removal Technologies by Manish Kumar,Sanjeeb Mohapatra,Kishor Acharya Pdf

With an increased demand for wastewater reuse, groundwater recharge with treated wastewater has been practiced across the globe. As a result, groundwater quality deteriorates by emerging micropollutants from various anthropogenic origins, including untreated wastewater, seepage of landfill leachate, and runoff from agricultural lands. The fate of such emerging and geogenic contaminants in subsurface systems, especially in the groundwater, depends on several factors. Physicochemical properties of contaminants such as octanol-water partition coefficient, dissociation constant, water solubility, susceptibility to biodegradation under anaerobic conditions, and environmental persistence under diverse geological and pH conditions play a critical role during subsurface mass flow. Thus, advanced wastewater treatment techniques, followed by implementing stricter guidelines, are some of the measures that can safeguard water resources. This book, in general, gives an understanding of the fate and mitigation strategies for emerging and geogenic contaminants in the groundwater. The first and second sections provide a detailed insight into various removal techniques and mitigation approaches. Possible treatment strategies, including bioremediation and natural attenuation, are also covered in those sections. Environmental assessment, groundwater vulnerability, health effects, and regulations pertaining to various contaminants are systematically presented in the third section.

Emerging Contaminants Handbook by Caitlin H. Bell,Margaret Gentile,Erica Kalve,Ian Ross,John Horst,Suthan Suthersan Pdf

The term "emerging contaminants" and its multiple variants has come to refer to unregulated compounds discovered in the environment that are also found to represent a potential threat to human and ecological receptors. Such contaminants create unique and considerable challenges as the push to address them typically outpaces the understanding of their toxicity, their need for regulation, their occurrence, and techniques for treating the environmental media they affect. With these challenges in mind, this handbook serves as a primer regarding the topic of emerging contaminants, with current and practical information to help support the goal of protection where they are encountered. Features Explores the definition, identification, and life cycle of emerging contaminants. Reviews current information on sources, toxicology, regulation, and new tools for characterization and treatment of: 1,4-Dioxane (mature in its emerging contaminant life cycle) Per- and polyfluoroalkyl substances (PFASs; a newer group of emerging contaminant) Hexavalent chromium (former emerging contaminant with evolving science) 1,2,3-Trichloropropane (progressing in its emerging contaminant life cycle) Provides thoughts on opportunities in managing emerging contaminants to help balance uncertainty, compress life cycle, and optimize outcomes.

Emerging Contaminants by Kathleen Sellers,Denice K. Nelson,Nadine Weinberg Pdf

Emerging Contaminants: Anticipating Developments examines the factors that have led "new" environmental contaminants to emerge in the past and combines the lessons learned to anticipate potential new developments. The analyses described in this book originate in multiple disciplines: the science of toxicology; environmental law and regulation; the field of product stewardship; and the social science which explains why ideas take hold. Over a dozen case studies of contaminants that emerged as environmental issues over the last hundred years illustrate crucial points. The results of the analyses in this book support a step-by-step method to assess the potential for a contaminant to emerge, and a framework to apply those conclusions to managing site liabilities. Features: Describes an unprecedented understanding of why contaminants emerge as issues, based on a multidisciplinary analysis Makes abstract concepts tangible, basing analyses on data and illustrating key points with case studies Enables readers to anticipate and prepare to manage future challenges associated with emerging chemicals Presents an analytical framework for companies to assess and manage business risks Written for regulators, policymakers, industry professionals with responsibility for contaminated site management, as well as attorneys, and consultants, this book provides a framework for anticipating the emergence of new contaminants so that the risks–whether to human health and the environment or to a business–can be anticipated and appropriately managed.

Strengthening Forensic Science in the United States by National Research Council,Division on Engineering and Physical Sciences,Committee on Applied and Theoretical Statistics,Policy and Global Affairs,Committee on Science, Technology, and Law,Committee on Identifying the Needs of the Forensic Sciences Community Pdf

Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Electrochemistry for the Environment by Christos Comninellis,Guohua Chen Pdf

Wastewater treatment technology is undergoing a profound transformation due to the fundamental changes in regulations governing the discharge and disposal of h- ardous pollutants. Established design procedures and criteria, which have served the industry well for decades, can no longer meet the ever-increasing demand. Toxicity reduction requirements dictate in the development of new technologies for the treatment of these toxic pollutants in a safe and cost-effective manner. Fo- most among these technologies are electrochemical processes. While electrochemical technologies have been known and utilized for the tre- ment of wastewater containing heavy metal cations, the application of these p- cesses is only just a beginning to be developed for the oxidation of recalcitrant organic pollutants. In fact, only recently the electrochemical oxidation process has been rec- nized as an advanced oxidation process (AOP). This is due to the development of boron-doped diamond (BDD) anodes on which the oxidation of organic pollutants is mediated via the formation of active hydroxyl radicals.

Implications and Consequences of Anthropogenic Pollution in Polar Environments by Roland Kallenborn Pdf

The first evidence on the adverse effects of organic pollutants on Arctic ecosystems was provided by international research initiatives more than 30 years ago. Today, the indigenous people of the North are considered to be affected by exposure to persistent organic pollutants (POPs) and metals through their traditional marine food sources. The occurrence of pollutants of emerging concern in remote Polar environments is considered an essential criterion for prioritising this (largely neglected) type of contamination in national, international and global regulation schemes. Initiated during the first international Polar Years (IPY 2007-2009) and continued afterwards, 11 representative initiatives and projects are summarised as chapters in this book, which highlights today’s interdisciplinary research on POPs in the Polar environment. The individual chapters describe in detail the consequences, priorities and perspectives of international research on POPs (legacy and emerging xenobiotics), its implications for regulations and scientific priorities including societal and cultural developments in the Arctic, as well as conservation priorities in Antarctica. This book is intended for all readers interested in learning more about modern research on environmental pollutants in the Polar environments (with a strong focus on Arctic environments). The impacts of pollution and climate change on Polar regions and the world as a whole will continue to be felt for many years to come. Sound science is, thus, vital in order to underpin actions that need to be taken at the global, regional and local levels. This book contributes to this highly relevant, interdisciplinary environmental scientific endeavour.
